An agent-based tool for infrastructure interdependency policy analysis. (open access)

An agent-based tool for infrastructure interdependency policy analysis.

Complex Adaptive Systems (CAS) can be applied to investigate complex infrastructure interdependencies such as those between the electric power and natural gas markets. These markets are undergoing fundamental transformations including major changes in electric generator fuel sources. Electric generators that use natural gas as a fuel source are rapidly gaining market share. These generators introduce direct interdependency between the electric power and natural gas markets. These interdependencies have been investigated using the emergent behavior of CAS model agents within the Spot Market Agent Research Tool Version 2.0 Plus Natural Gas (SMART II+).

ARM/GCSS Single Column Model (SCM) Intercomparison Procedures for Case 3: Summer 1997 SCM IOP (open access)

ARM/GCSS Single Column Model (SCM) Intercomparison Procedures for Case 3: Summer 1997 SCM IOP

The Atmospheric Radiation Measurement (ARM) Program is a multi-laboratory, interagency program that was created in 1989 with funding from the U.S. Department of Energy (DOE). The ARM Program is part of DOE's effort to resolve scientific uncertainties about global climate change with a specific focus on improving the performance of general circulation models (GCMs) used for climate research and prediction. These improved models will help scientists better understand the influences of human activities on the earth's climate. The objectives of the ARM Program are: (1) to relate observed atmospheric radiation to the temperature and composition of the atmosphere, especially water vapor and clouds, across a wide range of climatologically relevant possibilities, and (2) to develop and test improved parameterizations of radiation and radiative interactions with water vapor, aerosols, and clouds, for use in GCMs.

A Collapse Surface for Perforated Plates with Triangular Patterns for Ligament Efficiencies Between 0.05 and 0.50 (open access)

A Collapse Surface for Perforated Plates with Triangular Patterns for Ligament Efficiencies Between 0.05 and 0.50

Collapse surfaces are developed for thick perforated plates containing a triangular penetration pattern with ligament efficiencies of 0.05, 0.10, 0.15, 0.2, 0.3, and 0.5 using elastic-perfectly plastic FEA analysis. The FEA data was fit to a fourth-order collapse function which is appropriate for the development of an equivalent solid elastic-perfectly plastic plasticity model for perforated plates with triangular penetration patterns. This type of model can be conveniently used to develop a limit load capability for perforated plate analysis. It was shown that the fourth-order function is reasonable for ligament efficiencies between 0.15 to 0.5. Comparing the fourth-order collapse function to FEA data suggests that an alternate collapse function is needed for ligament efficiencies less than 0.15. A linear interpolation method was shown to be appropriate for ligament efficiencies between 0.15 and 0.5.

Computation of Detection Efficiencies for NMIS Fast Plastic Scintillators Using a Thick Detector Model (open access)

Computation of Detection Efficiencies for NMIS Fast Plastic Scintillators Using a Thick Detector Model

This report describes and compares the computation of the detection efficiencies for fast plastic scintillating detectors from their Time-of-Flight (TOF) spectrums using two different detector models. In the first method which assumes a thin detector model, a one-to-one correspondence between the energy of the neutron and the time bin in which it appears in the TOF spectrum is used in computing the detector efficiencies. In the second method which is based upon a thick detector model, the macroscopic cross sections of the detector materials are used to determine the path length of a neutron in the detector and hence its time of detection. With this model, neutrons of a given energy E{sub n}, are distributed across several time bins in the TOF spectrum.

Courthouse Construction: Sufficient Data and Analysis Would Help Resolve the Courtroom-Sharing Issue (open access)

Courthouse Construction: Sufficient Data and Analysis Would Help Resolve the Courtroom-Sharing Issue

A letter report issued by the General Accounting Office with an abstract that begins "The judiciary is in the midst of a multibillion-dollar courthouse construction program. New courthouses are being built to house new judgeships created because of increasing caseloads and to replace obsolete courthouses occupied by existing judges. For years, there has been a debate about whether district judges could share courtrooms to save taxpayer dollars without compromising judicial administration. In 1997, GAO issued a report calling for better courtroom use data and analysis to enhance facility planning. In response, the Administrative Office of the U.S. Courts (AOUSC) contracted with Ernst & Young to study the judiciary's facilities program in 1999. As part of the study, AOUSC asked Ernst & Young to analyze courtroom utilization, assignment, and sharing by judges. GAO found that the Ernst & Young study did not provide the type of data and analysis that GAO and other research organizations, such as the Rand Institute for Civil Justice and the Federal Judicial Center, have determined would be needed to help resolve the courtroom-sharing issue."

Experimental assessment of gradient plasticity (open access)

Experimental assessment of gradient plasticity

Classical plasticity theories generally assume that the stress at a point is a function of strain at that point only. However, when gradients in strain become significant, this localization assumption is no longer valid. A common factor in the failure of these conventional models is that, since they do not account for the strain gradients, they do not display a size effect. This effect is seen experimentally when the scale of the phenomenon of interest is on the order of several microns. At this scale, strain gradients are of a significant magnitude as compared to the overall strain and must be considered for models to accurately capture observed phenomena. The mechanics community has been actively involved in the development of strain gradient theories for many years. Recently, interest in this area has been rekindled and several new approaches have appeared in the literature. Two different approaches are currently being evaluated: one approach considers strain gradients as internal variables which do not introduce work conjugate higher order stresses, and another approach considers the strain gradients as internal degrees of freedom which requires work conjugate higher order stresses. Experiments are being performed to determine which approach models material behavior accurately with the …

Fundamental studies of ceramic/metal interfacial reactions at elevated temperatures. (open access)

Fundamental studies of ceramic/metal interfacial reactions at elevated temperatures.

This work characterizes the interfaces resulting from exposing oxide and non-oxide ceramic substrates to zirconium metal and stainless steel-zirconium containing alloys. The ceramic/metal systems together were preheated at about 600 C and then the temperatures were increased to the test maximum temperature, which exceeded 1800 C, in an atmosphere of high purity argon. Metal samples were placed onto ceramic substrates, and the system was heated to elevated temperatures past the melting point of the metallic specimen. After a short stay at the peak temperature, the system was cooled to room temperature and examined. The chemical changes across the interface and other microstructural developments were analyzed with energy dispersive spectroscopy (EDS). This paper reports on the condition of the interfaces in the different systems studied and describes possible mechanisms influencing the microstructure.
